Application filed March 20, 191 Serial No. 829,015.

To (1/ l 'llf/EOHL it may concern. Be t known that I, iinnmcnrcn M.WHYTE,

a citizen of the United States of rrmerica,

ments in Unlocking Mechanism vfor ar- Couplings, of which the followingis a specifieation, reterenre being had therein to the accompanyingdrawings.

The inrention relates to merhanisnrfor unlockingcar couplers, andcomprises the novel construction as hereinafter set forth.

in the drawings: Figure 1 an elevation of the mechanism as applied tothe end of a car; Fig. is a plan view thereof; Fig. 3 is a. erosssection.

A the eoupler ioching pin of a car coupier (not shown).

B is a. l0(i formed with a crank or later ally-deflected portion C atthe outer end thereof, preferably having an operating handle D.

F is a bracket preferably having a. rounded arm E which engages anaperture F near the inner end of the bar B. The outer end of this arm Eis providedwvith n rerti-- caliper-Lending pivot-E which engages the eyeG of a rottii extending into engagement 7 with the pin A. The in er endot' the rod B bentoutward to form a laterally-extending arm 13 whichpasses beneath the.

rod. 2111a forms a. support therefor.

J bracket which forms a. guiric for the vertical movement the bar (I,and aiso a fuicrum for said bar when rotated .hy the turning of thecrank With the construction as described in op-' eration, the iochingpin A may he raised by operating the rod C, either as a lever; the

outer end of which. is depressed, or a.

In the nrst operatitm the bracket F acts as a fulcrum for both the leverB and the rori iii, which together constitute. a. compound iercr, thelateral arinIB" h tting the, rod This movement of the rod .ii. ispernntt-eo i v "A- 'i' i 5 r *l' nr'rn' m 1mi inc eye tneuio suiu ant.in; s,

comprising a rod having ;at itsi outer end,

the lateral extension of said first-mentioned rod and having itsopposite end engaged with the coupler locking member.

- 5. A car coupler unlocking mechanism, Comprising a rod having anactuating crank a lateral extension at its inner, end and anapertureinter nediate its ends, a bracket having throughsaid apertureand terminating in a shouldered .pin, a second rod having an eye at oneend loosely engaging said shouldered pin to form a universaL pivotalconnection therewith; said rod passing over the lateral extension ofsaid first-mentioned rod and engaging the coupler looking with itsopposite end. i

6; A car .eoupler unlocking mechanism, laterally deflected a curved armpassing' portions at its opposite end and apertured intermediateitsends, a bracket engaging said aperture and permitting the angular movment of said rod thereupon, a secon rod resting intermediate its endsupon the lateral y deflected portion of said first-men- .tioned rod andprovided with a pivotal support at its inner end upon said bracketermitting of a movement in a horizontal p ane independent of saidfirst-mentioned rod, to compel a vertical movement with said rod wheneither rocked or tilted.

In testimony whereof I aiiix my signature in presence of two witnesses.
